I like Google and Facebook. They provide a lot of value to a lot of people, invest in R&D, and contribute to the open source community. The same can be said of most monopolies, like AT&T in the 70's , Bell Labs did top notch research, and the highly reliable phone network provided huge value to people and businesses alike. Although it did have high value, it also had a high cost to the consumer and few people want to go back to the days of paying $30/month for local phone service (plus $3.99 if you want to use touch tone), and spending $7 for a 10 minute cross country call.
